Title: Improvements in or relating to fittings for use with boots, shoes and the like
IPC: A43B23/16
Filed: 1924-08-24
Abstract: 243,072. Tennick, P. M. Aug. 21, 1924. Addition to 238,025. Socks.-Guards for foot coverings made on the same principle as that described in the parent Specification are applied to other parts of the foot, viz., the toe, the sole, and lateral parts. Modification is also made in the heel guard of the prior invention. A flexible strip 11, Fig. 1, of material such as rubberized canvas which will afford, as in the prior invention, greater friction between the rubber surface and a sock than between the canvas side and a shoe, has a recess 12 cut in it. The upper edge 10 of the strip is convex and the lower edge 11 straight. The edges 11 are placed together and may be secured by an overlying strip 14, Fig. 4. One purpose of the recess 14 is to allow for ventilation. The overlying part 14 may be extended to form a shoe sock, but its dimensions will be such as to allow the necessary free yielding and sliding movement in company with the foot. A toe guard is formed similarly from a recessed strip as in Fig. 2, the edges 111 being brought together, leaving a recess at the toe. A sole guard 17, Fig. 4, may be used independently of the heel and toe guards. Any particular portion of the foot covering may be similarly protected. Specifications 17427/15 and 187,284 are referred to.

To renew the wearing surfaces of the strips the strips are turned over and each changed to the opposite track. The ends g of the strips are inclined to minimize noise when the rollers pass from one strip to the next.

Abstract: 839,045. Bakers' ovens. TANCRED & LANGLEY Ltd. Sept. 19, 1958 [June 25, 1957], No. 19974/57. Class 51 (2). A baking oven is divided into several superposed chambers 8 by horizontal hollow heating elements 9 forming part of a closed circuit for hot gases supplied by an oil burner 7 discharging through a combustion tube 5 into a rear oven space, said elements terminating short of the oven side walls whereby spaces are left to receive the side structure of a wheeled trolley 13 formed with transverse supports 16 at each chamber level for trays of food. A fan 6 discharges the hot gases into a vertical flue 4 communicating with each heating unit through inlets 11 controlled by dampers 19 actuated by spindles 20 extending through the oven side walls. Each element 9 is formed in its upper wall with transverse slots 12 discharging the hot gases into the baking Chamber immediately above. The gases escape through the open sides of the chambers for re-circulation to the rear space 3 and the fan 6, excess gases escaping through an upper flue 17 under control of a damper 18. The insulated door 2 closes against the front end of the heating elements 9 and one or more auxiliary doors are formed therein to provide independent access to single chambers. The slots 12 may be dispensed with and the baking chambers closed by baffles on the trolley 13.

Title: Improvements relating to the treatment of yeast
IPC: C12N1/38
Filed: 1936-07-20
Abstract: A small amount of a phosphatide, e.g. lecithin or cephalin is added to a yeast fermenter before, during or after propagation or to the yeast before or during the pressing stage.  A small amount of an emulsifying agent may also be incorporated in the yeast.

Title: Improvements in methods of reducing noise in telephone circuits
IPC: H04B3/30
Filed: 1926-08-18
Abstract: 259,546. Standard Telephones & Cables, Ltd., (Assignees of McCurdy, R. G.). Oct. 7,1925, [Convention date]. Two-way repeating systems ; induction, preventing and minimizing; phantom-circuit systems.-To reduce noise in systems in which a number of four-wire circuits run in a multiple cable between repeating points, the circuits are drained at points where the power level is comparatively high, e.g. at the output of the repeaters. This is effected by grounding the midpoint of an impedance connected across each circuit. In the system described the circuits are grouped in pairs and phantomed. The mid-points of the line sides of the phantom output transformers are grounded as at 5 in repeater E. This drains the side as well as the phantom circuits. The incoming circuits are not drained, but draining the others, which occupy the outer positions on the cable, has a shielding effect on them. At a point between repeating points at which the power level on both sets of quads becomes equal, they are transposed, the W-E circuits occupying the outer positions from this point to repeater W at which they are drained as at 7.

A blown airfoil member has two sets of differently-angled spanwise-extending slots 14A, 14B from which air may be blown tangentially over the surface to induce circulation, the arrangement being such that air may be blown through one set of slots to induce circulation in one direction or through the other set to induce circulation in the other direction or air may be blown in both directions at once to reduce drag. The air supply enters through a hollow liner 12 which has ports 13 cut in its outer surface and may be rotated so that different slots are covered. By suitably dimensioning the ports it is possible to shut off the blowing completely.

[Class 104 (ii)] A four-wheeled overhead trolley assembly adapted to be supported for dirigible movement along the substantially horizontal webs of a supporting track comprises a pair of trolley brackets spaced longitudinally along a track provided by the bottom flanges 11 of an I-beam 10, each bracket consisting of a pair of oppositely disposed identical bracket members 13 each with a single trolley wheel 12 mounted at its upper end upon a substantially horizontal axis 14, and a single means 24 for connecting the oppositely disposed bracket members together at their lower ends in lateral spaced relationship. The means 24 comprises a cylindrical member with a pair of diametrically prejecting trunnions 25 which extend in opposite directions into bearing apertures provided in the lower ends 23 of the bracket members 13, and provide a pivotal mounting for a bolt 29 extending axially through the member 24, the two bolts 29 thus mounted in the trolley providing support for an inverted channel 28 to which the limbs of a U-shaped load-attaching member 39 are pivoted intermediate the ends of the channel.
